TPC 300 max voltage out

• (L,M & H) Use to set the mode and voltage to the track. There are three different settings. • L Sets to command mode, supplying full input voltage to track • M Sets to conventional mode and resets speed limit to maximum • H Sets maximum speed in conventional mode • (HALT) Turns the track power off to all IC Controls products including the TPC3000 • (SET) With the run/program switch in the RUN position • Saves conventional or command mode settings

I reread manual I misunderstood theM key followed by turning red knob full blast then push h key to save maximum speed limit.

Will try later see what happens.

When I used the TPC 300, I connected 2, 135 watt bricks to it for Power. This gave me the power I needed to run practically 18 volts to the track.  We use Legacy almost exclusively.  The really neat feature of the TPC is friends can run Conventional with the M button....Wow.  The L is for legacy 18 volts to the track. The M is for Conventional with power adjustment 0 to 18 volts..The H setting for our engines.... Command Control has really given Our Hobby a technical advantage....

Ok I made sure speed limit set to maximum pushed m key red knob until passenger lights full on then pushed h key.

then I pushed aux1 and then 9 key I now have 17.12 volts into tpc and 16.10 volts output from tpc.

Things are working much better now.

I have the same set up.  My Lionel 180 w brick puts out 18 volts.

But when all is hooked up with no track power usage by anything else I am only getting 16.1 volts on the track.

Wondering what you are getting at track level and why a 2 volt drop.....does the TPC require the lost voltage?

Thanks

My 180 brick supplied a little over 18V (measured by a fluke TRUE RMS) meter to my TPC-300.   The TPC outputted about the same to the track, so I reduced it to 17V, where it's stayed (in TMCC mode).    I haven't measured max-V in conventional.

well well a senior moment!!  the power source is not from a 180 watt powerhouse but from the max transformer with adjustable rheostat so I set it at 20 volts and get 18.11 volts at track with a  2amp draw.

so I used voltmeter to set track at 13.11 volts while the polar express steam and 3 passenger cars are rolling it is running well and is smoking well at this speed.
